Like title states check engine light came on stayed on for a little then randomly went off on its own and did not come back on. I scanned it with the obd1 scanned I get 6 codes. 10,121,176,511,542,543.
1995 for mustang gt 5.0
I'm thinking fuel pump is going bad? 2 codes 542and 543 are to do with fuel pump. 1 code is rom failure. one code is to do with voltage to high, 1 is to do with 02 sensor.
Codes definition are as follows:
10= n0 defition for it?
121= closed throttle voltage higher or lower then expected
176= hego)ho2s) sensor fault/always lean
511=read only memory (rom test failure)
542= fuel pump secondary circuit fault
543= fuel pump secondary circuit fault
What do you guys think ? where to go from here
